Selective Infarction of the Anterior Genu Fornices Associated with Giant Cell Arteritis

Acute-Onset Anterograde Amnesia Caused by Isolated Bilateral Fornix Infarction

“…Until recently, there have only been two cases of isolated infarction of the bilateral anterior fornices reported, one attributed to small vessel disease 7 and another case attributed to giant cell arteritis. 8 We present an additional case of isolated bilateral anterior fornix infarction. This entity is likely underrecognized, and should be considered in patients presenting with acute-onset anterograde amnesia and risk factors for stroke.…”

“…2 Non-traumatic, acute-onset anterograde memory loss due to bilateral fornix infarction is rare, with few cases reported in the literature (Table). [3][4][5][6][7][8] Four of these cases also had concomitant anterior callosal infarction. [3][4][5][6] This may be explained by the fact that the short branches of the anterior communicating artery, which supply the columns of the fornix, commonly supply the anterior corpus callosum, septal nuclei and anterior cingulum.…”

Acute amnesia caused by left fornix infarction: A case report of an unusual entity

“…Direct unilateral fornix injury with resultant memory impairment secondary to accidental trauma or iatrogenic causes from cerebral intervention like surgical resection have been described in case reports [ 4 , 5 ]. Pathophysiological causes such as vasculitis, cardioembolism, and even pregnancy-related pathology have been shown to cause bilateral forniceal injury leading to memory impairment [ 6 , 7 ].…”

Acute amnesia during pregnancy due to bilateral fornix infarction: A case report

“…Iatrogenic subcallosal artery occlusion after clipping or surgery of the anterior communicating artery can also cause acute amnestic syndrome. However, the patients in the previous reports[ 5 , 11 - 15 ] did not represent young-age pregnancies without risk factors of ischemic stroke or cerebral vascular abnormality.…”
